PROFESSIONAL EXPERIENCES
| Present – September 2021 | Associate Professor of Aerospace with a courtesy appointment in Material Science Texas A&M University, College Station, TX, USA My research goals are to predict the mechanical behavior of materials (metallic and ceramic) at high temperature by means of a multi-scale approach using experimental (high temperature mechanical testing, microstructure observation, tomography, etc.), theoretical (crystal plasticity, phase field, etc.) and computational tools (finite element simulation). |
